The LEGO® Technic Idea Book: Wheeled Wonders is a collection of hundreds of mechanisms for cars, trucks, motorcycles, and other vehicles that you can build based on their pictures alone. Each project uses color-coded pieces and is photographed from multiple angles, making it easy to see how the models are assembled without the need for step-by-step instructions. Every model illustrates a different principle, concept, or mechanism that will inspire your own original creations. You're encouraged to use these elements as building blocks to create your own masterpieces.

The Technic models in Wheeled Wonders spin or move things, drag race, haul heavy gear, bump off walls, wind up and go, and much more. You'll discover how to build differential gears, implement steering and suspension, and design clutch and transmission systems to use in your own vehicles.

This visual guide, the second in the three-volume LEGO Technic Idea Book series, is the brainchild of master builder Yoshihito Isogawa of Tokyo, Japan. Each title is filled with photos of Isogawa's unique models, all of which are designed to fire the imaginations of LEGO builders young and old.

Imagine. Create. Invent. Now, what will you build?

NOTE: The LEGO Technic Idea Book series uses parts from various Technic sets. If you don't have some of the pieces shown in a particular model, experiment by substituting your own parts or visit the author's website for a list of the special parts used in the book.

"These are excellent books showing a lot of great ideas for LEGO mechanisms. Even if you're an experienced builder, there are surely some ideas in here you've never seen."
—Brickpile (Read More)

"What I like about these cool little models is that they can be used to teach various science concepts such as gearing, Newton's Laws, and Potential & Kinetic energy—to name a few."
—The Robotic Realm (Read More)

"For anyone who loves Lego, prototypes in Lego, or loves mechanical assemblies, these books are definitely required viewing, and we're not sure how we lived without them for so long."
